LAMP-CORD ADJUSTER.

To all whom it may concern:

Be it known that we, WILLIAM HAosTnoM, EMANUEL f-Lxesrnoir, and GUSTAFHAosTnoM, citizens of the United States of America, and residents ofLindsborg, county of Mo- Pherson, and State of Kansas, have inventedcertain new and useful Improvements in Lamp-Cord Adjusters, of which thefollowing is a specification.

Our invention relates to lamp cord adjusters, and has for its objectimprovement in the construction, operation and convenience of suchdevices.

In the drawings, Figure 1 is an elevation; Fig. 2 is an enlargedelevation of the interior parts, the halves of the casing being slightlyremoved and shown in section; Fig. 3 is an elevation from the right ofthe parts shown in Fig. 2, the casing being closed; Fig. 4 is a sectionof the operating parts; Fig. 5 is a section of part of the casingshowing the means for locking them together, and Fig. 6 is a detachableperspective view of the ratchet device.

In the said drawing, 10 is a shaft on which is secured a reel 11 and aclock spring 12 arranged to turn the reel so as to wind thereon a cord19 which consists of two branches extending upward and downward from thereel. These parts are carried in a frame 13 which consists of two halvesalike in form, but placed together so that the joints are not in linewith each other. At the places where these halves are secured togetherthere are supported blocks 14 which serve as guides for the branches ofthe cord 19. As will be seen in Figs. 2 and 4 these guides are not inline with each other and are not opposite the center of the reel 11. Theobject of offsetting these guides in this manner is to direct the twobranches of the cord to different parts of the reel so that when thecord is wound thereon it will not pile upon one part of the reel, butwill have a better distribution than would be the case if these guideswere in line with each other. Secured to the end of the shaft 10opposite the end on which the spring is secured is a notched wheel 15,against the inner face of which presses a spring 16 having a smallprojection 17 on the face thereof, adapted to engage the notches of thewheel 15. At the upper end of the spring 16 is a push button 18, bymeans of which the spring 16 may be pushed away from the notchedSpecification of Letters Patent.

wheel so as to remove the projection 17 therefrom and'permit the spring12 to turn thereel 11 so as to wind the cord 19. These various parts areinclosed by a casing made up of an upper half 20 and a lower half 21.These halves are alike except that the upper half has its center orequatorial portion bent outward, as shown at 22, so that the part 21 mayjust enter within it in very much the same manner that the bottom of anordinary tin box enters into the cover thereof. These two halves of thecasing when put together form a smooth exterior casing, the general formof which is a prolate ellipsoid. In the lower half 21 is a piece ofcurved spring wire 23, which has its ends bent around so that they maypass through the registering holes in the two parts of the casing at theplace where they come together. This spring thus forms a locking devicefor the two casings and this locking device rests within the case whenit is put together so that the only appearance on the outside is theextreme end of the wire which appears as a mere spot on the central bandof the casing. By pushing one end of this wire inward the halves of thecasing are released and the casing itself may be opened. This lockingdevice is entirely concealed from ordinary observation, but is in such aform that it permits the two halves to be put together quickly andeasily and also permits them to be easily and quickly separated. At theextremities of the major axis of this ellipsoid are two openings intowhich the rounded ends of the blocks 14 project and fit so that theoperating parts and the case are held securely together, as previouslymentioned. These guides are not in a line with each other with respectto the axis of the reel 11. The result of holding these guides in thetwo holes which are themselves the ends of the axis running through thecasing, is that the shaft 10 does not lie exactly perpendicular to theaxis through the casing, but is slightly inclined to such perpendicularline. This will readily be seen by examination of Fig. 2. In that figurethe halves of the casing 20 and 21 are shown in a line with the guides14. It will be evident that by bringing these cases toward each other sothat the guides 14 would fit into the holes in the halves of the casingthese halves themselves would not be in a position to unite or enter oneinto the other.

By moving them over so that one will enter the other, such movementwould incline the axis of the reel with respect to the major axis of thecasing. In the side of the upper casing is an opening through which thepush button 18 extends so that said push button may be operated from theexterior of the case.

What we claim is:

1. An inclosing case for the operating parts of a cord adjuster,consisting of two substantially semi-ellipsoidal shaped sheet metalshells one of which has an annular outward bend at its larger end andthe other of which shells has its larger end fitting within said annularoutward bend, and a locking device consisting of a curved substantiallybow-shaped piece of spring wire lying wholly within one of the shellsand having its ends bent outwardly so as to pass through registeringholes in the two shells where one enters the other.

2. In a lamp cord adjuster, a reel, a spring for operating said reel soas to wind a cord thereon, a notched wheel secured to and moving withsaid reel, a spring bearing against the face of said wheel and having aprojection thereon adapted to engage one of the notches in said wheeland hold it against the action of said spring, a casing inclosing saidparts so as to form a smooth e:; terior therefor, and a push buttonconnected to the last named spring and projecting through an opening insaid casing.

23. In a lamp cord adjuster, a reel and means for operating it so as towind a cord thereon, a notched wheel secured to said reel,

a catch adapted to engage the notches of said wheel, an ellipsoidalcasing inclosing said parts, and a push button connected to said catchand extendingthrough an opening in said casing.
